Software designed to streamline the use of Manual J calculations, a cloud-based collaborative inventory management solution, service management software for contractors with residential and commercial clients and more.

Cool Calc Manual V2.1 (DCNE, is designed to streamline the use of Manual J calculations to determine the capacity of HVAC equipment when designing a home HVAC system. The app, which is compliant with ANSI/ACCA 8th Ed V2, can be used on any internet-enabled computing device. It allows users to quickly trace a home in Google Maps and obtain all the dimensions of a home’s footprints, ceiling, floor, and wall areas, and building exposures, which are used to perform block load and room-by-room calculations.

Utilizing the year in which the house was built, the software will automatically select the appropriate construction materials based on similar homes in the area and the version of the energy code adopted by that county at the time of construction. The app allows users to model any number of system scenarios, including a ducted versus ductless system or a single large system versus multiple small systems. 

The V2.1 version can integrate with third-party solutions, such as magicplan, which leverages the camera on a mobile device and augmented reality to create a floor plan of the home, or into other third-party applications such as eCommerce sites and proposal tools.

There is no cost to create an account for Cool Calc, but there is a sliding fee for downloading or printing the official ACCA Manual J v.8 reports, based on the quantity of reports in the purchased pack.
